To all whom t may concern:

Be it known that I, HARRY W. GRIFFITH, a citizen of the United States of America, and resident of Ault, vWeld County, Colorado, have inventeda new and useful Tobacco Pipe, of which the following is a speciiication.

An object of this invention is to provid improved means for cleaning a tobacco pipe, particularly in respect to the smoke duct therein.

A further object of this invention is to provide an improved construction for tobacco pipes, whereby the smoke duct therein may be exposed for cleaning purposes.

A further -object of this invention is to provide an improved construction for tobacco pipe, whereby the bottom of the bowl thereof may be exposed for cleaning purposes.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation of one form of my improved pipe. Figure 2 is a bottom plan of the same, the lower-most member being removed, partly in section. Figure' is a top plan of the lower-most member removed from the remaining elements. Figure 1 .is a cross section on the indicated line 1 4 of Figure 1.'

In the construction of the tobacco pipe as hereinafter shown and described, the

bowl and shank portions thereof are divided substantially on a right line and thus formed in two mating members. This construction. is applicable either to a pipe of the straight type as shown, or pipe of the curved stem type. The upper-most member 10l of the pipe contains a portion, probably the larger portion, of the bowl and a portion of the shank, and the lower member 11 of the pipe contains the remainder of the bowl and the remainder of the shank. The adjacent faces of the upper and lower members 10, 11 are plane, except that dovetail grooves 12-13 are formed in the upper face of the lower member `and are adapted to receive, and slidingly engage, dove-tail ribs 111-15 of the upper member. Substantially one-half of the smoke duct 1G is formed in each of the upper and lower members, and the same is on the median line of .the members .and between the respective grooves and the respective ribs. (Other dove-tail grooves 17, 18 are'formedin the lower member 11, in line with the grooves 12, 13 and on the oppositesidefof the'bowl cavity therefrom, and when soprovided are adapted to slidingly engage with other `dove-tail ribs 19, 20, formed kon the member 10 in line with the ribs 14, 15. A relatively small concave portion of the tobacco cavity of the pipe is contained in the lower member 11 and indicated by the numeralk connection, with a socket formed in the outer end of saidv shank and confined Vby ferrule or band 23. IVhen the stem 22 is mounted in the socketfof the shank of the pipe a smoke duct 24 therein registers with the out-er end of the smoke duct 16. In Figure 2 I have shown the ferrule or band 23 in section and omitted it from Figure 3.

The lower member 11 ofthe pipe may be separated and withdrawn from the upper member and from the band or ferrule 23 by longitudinal outward movement effected manually and may be replaced by an opposite movement. When theparts are in position shown in Figure l, the upper and lower members .of the pipe are firmly connected by inter-engagement of the dovetail grooves and ribs. Vhen the parts of the pipe are separated halves of the smoke duct 16 are exposed and can readily be cleaned and the bottom of the bowl 21 also is exposed andl may likewise be readily cleaned. Also, the parts may be separated and exposed for aeration and the cleansing and purifying action of atmosphere.

I claim as my invention- 1. A tobacco pipe formed of separablek members adapted to be moved relative to each kother on right lines and parallel planes, said members being formed with mating portions of a smoke duct and also being formed with interengaging dove-tail grooves and ribs, the plane of separation between said members intersecting the bowl of the pipe.

2. A tobacco pipe formed of separable members, each containing a portion of a tobacco bowl or cavity, and also each containing a portion of a smoke duct communicating with said cavity, adjacent faces of said members'r being substantially plane and respectively formed with inter-engaging dove-tail grooves and ribs, eacli'member also being formed with 1a portion .of a stern Socket, said grooves extending from said socket through the bowl-end of the pipe. Y v Y 3. A tobacco pipe formed of separable members,V each Containing a portion of `a tobacco bowl or cavity7 and also each containing a portion of `a smoke duct coi-nmunicating withsaid cavity, adjacent faces of said members being substantially-plane andjrespeotively formed with nter-engage Y ing dove-tailgrooves andribs, each of said inenibers 'further being formed with a portion of stem receiving Socket, a stem detach- ,HARRY w.
